+Subject: qemu: tpm: do not update profile name for transient domains
+MIME-Version: 1.0
+Content-Type: text/plain; charset="utf-8"
+Content-Transfer-Encoding: 8bit
+
+If we do not have a persistent definition, there's no point in
+looking for it since we cannot store it.
+
+Also skip the update if the tpm device(s) in the persistent
+definition are different.
+
+This fixes the crash when starting a transient domain.
